Questions & Answers

As answered by people managing StemPlayer and StemRoller.

What makes your product unique?

StemPlayer's answer

Six stems with dedicated guitar and piano channels, opened straight in a practice mixer in the browser. You do not get a zip of files to take somewhere else: you mute your part, slow the song down without changing the pitch, loop a section and play along, all in one place, with nothing to install.

Why should a person choose your product over its competitors?

StemPlayer's answer

Moises and LALAL.AI are subscriptions and cap free use hard; Ultimate Vocal Remover is free but needs installing and a good graphics card. StemPlayer runs in any browser, on a laptop or a phone, is free while in beta, and is built for playing along rather than producing.

How would you describe the primary audience of your product?

StemPlayer's answer

Musicians who learn and practise songs by ear: guitarists, bass players and drummers who want to play their part with the real band, singers who need an instrumental, and teachers preparing play-along tracks for students.

What's the story behind your product?

StemPlayer's answer

I am a gigging guitarist, and learning a part from a record always meant fighting the original guitar in the mix. Stem separation fixed that, but every tool either charged monthly, stopped at four stems, or dumped files I had to load into a DAW. I wanted to drop in a song, pull my part out and play. So I built StemPlayer for my own practice and opened it up for other musicians.

Which are the primary technologies used for building your product?

StemPlayer's answer

  • React and Vite for the browser app, hosted on Cloudflare Pages
  • Web Audio API for the mixer, with time-stretching so a slowed-down song keeps its pitch
  • Python and FastAPI for the backend
  • Demucs, a neural network for music source separation, running on a cloud GPU
  • Browser storage (IndexedDB) for the song library, so songs stay on your device

Who are some of the biggest customers of your product?

StemPlayer's answer

  • StemPlayer is a free beta used by individual musicians: guitarists, bass players, drummers, singers and music teachers. It has no business customers.
